Eyebrows aren’t just key facial features — they can dramatically frame your face and convey emotion. But perhaps you overplucked them, suffered a waxing mishap, or are healing from hair loss due to a medical condition. The question is: how long does it take eyebrow hair to grow back?
Eyebrows typically grow back in a varying timeframe depending on a number of factors such as age, genetics, health, and the cause of hair loss. But knowing how it works and doing the right thing can accelerate the process. This blog discusses the factors affecting eyebrow regrowth with clear timelines while also providing pro tips for healthier and faster hair growth.
The Eyebrow Growth Cycle
Like all the hair on our bodies, eyebrows progress through a three-phase cycle of growth, rest, and fallout:
Anagen Phase (Growth Phase)
This is the phase when eyebrow hair grows actively. It lasts approximately 30–45 days, substantially shorter than the growth stage of scalp hair, which is the reason eyebrow hairs are shorter.
Catagen Phase (Transition Phase)
Hair growth halts at this phase, and it separates from the blood supply. It lasts for roughly two to three weeks.
Telogen Phase (Resting Phase)
The last phase lasts about 100 days, when brow hair falls out to make room for new growth.
This cycle means that the amount of time it will take for your eyebrows to fully regrow will vary, depending on where an individual hair is in its growth cycle.
How Long Do Eyebrows Take To Grow Back?
Eyebrow hair typically takes 3-4 months to grow fully, though this can vary depending on genetics, health, and other factors. Here’s what could affect how long that takes:
Reason for Hair Loss
- Dread: Hair removal procedures cause permanent damage to the hair follicle and hair does not regrow. If you’ve developed scars from over-plucking, some hairs may not ever grow back.
- Shaving: The eyebrows may grow back in about 4-6 weeks if you’ve shaved them, since the follicle under the skin isn’t affected.
- Medical Conditions or Treatment: Conditions including alopecia or treatments involving chemotherapy can lead to longer regrowth timelines—several months, in some cases, over a year—particularly if follicles were damaged.
Age
Like every other facet of the body’s machinery, hair growth slows as we age. Younger individuals might see faster regrowth, while older adults might notice that it takes significantly longer.
Genetics
How quickly your eyebrow hair grows back is dictated largely by your genes. Some people naturally have hair that grows more quickly than others.
Health & Nutrition
To some extent, hair responds to the general health and nutrient levels in your body. Poor nutrition or conditions that impact hormone levels (thyroid issues, for example) may cause regrowth to be delayed.

Brow Boost: How to Make Your Eyebrows Grow Back Faster
While we can’t entirely dictate how hair-follicle biology works, we can foster eyebrow regrowth with a handful of tried-and-true methods:
Avoid Overplucking
Over-plucking is one of the main reasons for sparse brows. Put down the tweezers for a few months, to give your brows a chance to grow in.
Use Nourishing Serums
Eyebrow serums with growth-amplifying ingredients such as peptides, biotin, or castor oil may strengthen your hair and increase regrowth rates. These are typically stocked at beauty retailers or online.
Hydrate and Moisturize
“If your brow area is hydrated, so is your skin, which allows healthy hair growth.” A little coconut oil or aloe Vera does wonders.
Reconsider Your Diet
Biotin, zinc, vitamins E and D, and omega-3 fatty acids are all essential nutrients for hair health. Foods such as eggs, salmon, nuts, and leafy greens are known to promote growth and thickness of eyebrows.
Massage the Brow Area
Massaging your eyebrows gently with your fingers increases blood circulation to the hair follicles, which leads to hair growth in a little time.
Stay Consistent with Care
Eyebrow growth takes time, so be patient. Give your efforts at least a few months before looking for substantial results.
Eyebrow Hairs That Don’t Grow Back
Occasionally, eyebrows fail to regrow as expected for a reason. Here are a few signs you might need professional help:
Patchy or Uneven Regrowth
If your brows are sparse or growing back unevenly, consult a dermatologist — they can test for scarred follicles or skin conditions.
Growth That Is Totally Stalled
If there is no regrowth for six months, or more, it does make sense to seek advice from a medical professional.
Gradual Thinning
Slow eyebrow thinning can indicate hormonal imbalances, such as hypothyroidism, or an autoimmune condition, such as alopecia.
In some cases, medical treatment — like corticosteroids or platelet-rich plasma (PRP) therapy — may help reinstate eyebrow growth.
Cosmetic Solutions for Sparse Brows
If your brow regrowth rate isn’t cutting it, there’s a suite of cosmetic solutions you can consider to get fuller-looking brows:
- Lip Fill: Another popular semi-permanent option, where a tattoo may be placed to define and fill in lip color.
- Brow Pencils or Powders: This type of product can easily fill in any sparse spots.
- Tinting & Lamination: Professionals can tint and sculpt existing eyebrow hair for added fullness.
Growth of Eyebrows Is a Process, Not a Sprint
The three pillars of successful eyebrow regrowth are patience, proper care, and healthy nutrition. However, although the timeline differs according to factors including age, genetics, and the cause of hair loss, taking action to support your brows can help make an obvious difference.
If you are having difficulty with regrowth or would like professional advice, see a dermatologist or a brow specialist. Keep in mind that full eyebrows are a bit of a time investment — and taking extra care of them now can pay off in months of beautiful, natural-looking brows.
